Add particle systems and visual effects to an FXGL game — configure ParticleEmitter with function-based setters (setVelocityFunction, setAccelerationFunction, setExpireFunction, setScaleFunction, setSpawnPointFunction); use built-in factory emitters (fire, explosion, smoke, rain); apply image-textured particles with multiplyColor / toColor; write custom per-particle physics via setControl; attach TrailParticleComponent for motion trails; apply SlowTimeEffect for bullet-time; apply WobbleEffect for screen-shake; stack multiple effects with EffectComponent; build fireworks displays. Use this skill when adding explosions, fire, smoke, rain, motion trails, impact bursts, bullet-time slow-motion, screen shake, or any particle-based visual polish.
Start a new FXGL project through a bounded Socratic discovery flow, then turn the answers into a docs-first starter specification with ADRs, an arc42-lite architecture summary, and Mermaid use-case diagrams before scaffolding the project itself. Continue using the same questioning approach for initialization choices, and require documentation updates plus automated tests for every implemented step.
Build a Breakout or Arkanoid style game in FXGL — control a paddle horizontally, keep a ball at constant speed, bounce it off walls, paddle, and bricks, load brick layouts from level data, angle the reflection based on paddle hit position, handle lives and bottom-drain loss, spawn falling power-ups, and finish the level when all breakable bricks are destroyed.
Build a first-person 3D game in FXGL — set up a player-driven Camera3D, implement mouse look, move relative to the camera facing direction, add a crosshair HUD, raycast or pick 3D targets, simulate gravity and jumping, and manage a first-person weapon or interaction model. Use this skill for FPS, first-person exploration, or first-person puzzle prototypes built on FXGL's 3D scene support.
Build an incremental idle or clicker game in FXGL — click for resources, buy auto-producers, scale costs exponentially, show passive income in the HUD, unlock upgrades by milestones, calculate capped offline progress on load, format very large numbers, and implement prestige resets with permanent bonuses.
Build a Metroidvania in FXGL — connect multiple platforming rooms, transition between Tiled maps at screen edges, gate progression behind movement abilities, persist room state and item pickups, add a map overlay for explored rooms, support save points and fast travel, and handle backtracking through an interconnected world.
Build a rhythm game in FXGL — parse a beatmap, spawn notes early enough to scroll into a hit zone on time, score inputs by timing window, handle combo and grades, support hold notes, and keep chart timing aligned with audio as closely as FXGL's current audio API allows.
Build a Snake game in FXGL — move on a discrete grid by timer steps, store the body as a deque of grid cells, grow when food is eaten, buffer direction changes, detect self-collision and wall rules, increase speed as the snake grows, and support multiple food types or wrap mode.
